We always make up the male adapters on copper pipe first. It saves dissasembly of the valves in many cases. But on the Hansgrohe, I believe they call for complete removal of the innards for flushing anyway. Those valves are amongst the most sensitive we have used, get call backs too often for leaks...so I refuse to install them any more. They also have a velcro faceplate attachment which usually fails...use silicone to reattach the velcro to the various parts, let it set a day, then reinstall...good luck.

: : Compression fittings are not allowed inside the walls. Use the sweat male adapters. Don't forget to disassemble the valve innards while soldering so close to the body.

: You can order most rough valves in sweat configuration; if you buy it at the Depot it will have threads.
